Roundabout Project Enters Next Phase of Work

PennDOT announced the next phase of the McLaughlin Run Road roundabout project in the Township of Upper St. Clair begins Friday, Nov. 5. 

Starting at 5 p.m. on Nov. 5, Lesnett Road will be unrestricted at the intersection of McLaughlin Run Road as crews enter the next phase of the project. Bi-directional traffic will be maintained in each direction as four temporary traffic signals will be utilized to guide motorists through the intersection. The decrease from six temporary signals down to four will allow traffic to cycle through the intersection at a faster rate. The configuration is expected to last through early spring 2022. 

Crews will work to build an arch culvert on Lesnett Road and continue to construct new sewer lines across McLaughlin Run Road. 

The overall roundabout project is expected to conclude in fall 2022. Plum Contracting, Inc. is the prime contractor.
